what's the trick?
3% of the ac rating.....

I have wa6... tt

me too :>

Whats answer to 2 1 18?

343

343?

A lot of wrong tests - is all you need for low AC rating.

I don't find mistakes in my program, but WA6 too
my prog returns:

10.0 1.0 1000000
179000001

10.0 9.9 1
1

1.1 1.0 12345
123456

10.0 10.0 10
0

"Impossible" answer never returns

4.4 4.3 1000000

Maybe 14926?

My AC program outputs
29851

AC rating became 2%
try to submit your code 50 times and you'll get AC:)))

How did you got that???
I use n*(y-x)/(1-y)

(14926+4.4*1000)/(14926+1000000)=4.34999793088..
((14926+4.4*1000)/(14926+1000000)):0:1=4.3

You formula is incorrect.
What if y == 1.0 ??? You are dividing by 0 ?

y:=y+0.05-eps

without rounding 1.0 will not be achieved

first:
not  (14926+4.4*1000)/(14926+1000000)=4.34999793088..
but  (14926+4.4*1000000)/(14926+1000000)=4.34999793088..

second:
not  (14926+4.4*1000)/(14926+1000000)=4.34999793088..
but  (14926+4449999)/(14926+1000000)=4.399261621


third:
(29851+4449999)/(29851+1000000)=4.349998204

Yes you are right - i've made mistake while printing:  1000 -> 1000000,
Thank you
but i don't understand how we
should compute not rounded X value

I think that this task  more harder than
it seems after first reading:)

x*n can be
X=(x+.05)*n
while (X/n>=x+0.05)X--

mine is also 29851, but i still wa@6.

I used y=y+0.05 in my program and get WA6.
Why x should be increased x=x+0.05?
